摘要
The wear resistance of carbon steels strengthened by plasma hardening in an UDGZ-200 setup is studied using a friction machine. It has been found that the wear resistance of hardened low-carbon steel 15 is equal to ∼70% of normalized steel 45, as well as the wear resistances of the hardened medium-carbon steel 45 and the hardened high-carbon U8A steel exceed the wear resistance of the normalized steel 45 by ∼60 and ∼90 times, respectively.
